Motivated by #156 (comment) and associated discussions, one could consider creating a lightweight package that performs loop analysis and unrolling (possibly other loop optimisation) using similar techniques for forward mode algorithmic differentiation (see, e.g. #389).

Mooncake could utilise these techniques before the autograd transform to address #156. One advantage of a lightweight package is modularity; the loop analysis and unrolling are not specific to Mooncake.

Packages like Valentin's https://github.com/vchuravy/Loops.jl perhaps provide a starting point for this kind of work. I agree that we shouldn't implement loop optimisations inside Mooncake itself -- that would put off potential collaborators, and make it harder for others to benefit from generic functionality.
